Application led )tay To all wlw/m.` it my convent-1 Be it known that I, WALLACE GALLEN- Dan, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois', have invented certain newv and useful Improvements in Measuring Stoppers .fori Bottles, of which the following is a" i specification.

communication vwit containerio receive a measured uantity of the contents thereof, -and therea yerV cut off from such" communication in order that the measured quantity of contentsma be disposed of without releasin more o the con#` ,tentsof the container; an accord1ngly,one feature of the invention. conslsts 1n providinga bottle stopper with a measuring cham.

ber, with a pnassageway throughwhich the measuring c mber communicates with the interior of the container, and with means. foiilopening and closing such passageway at w1 r Another object is to provide a construction of such a measuring ystopper which will insure freedom im the flow of the contents into the measuring chamber, and which may be opened and closed b relative movement between the stopper an the container; and, accordingly, another feature of the invention consists in providing the measuring chamber with a hollow stem projectingmto the mouth of the container and surrounded by a packing combined therewith in a manner to serve as a valve for opening and closing the passageway. A

Still another object of the invention 1s to provide a stopper for a bottle, or other container, having v,a chamber to receive a portion of the contents of the container, and so constructed that it will be especially adapted for disposal of the contents of the chamber in the particular manner that may required in the use for which the dev1ce is intended; accordingly,still another feature of the invention consists in constructing the wall of thechamber in various forms, such, for instance, as a mouth-piece convenientl received into the mouth of a patient in ag ministering medicine; an eye cup adapted to fit over the eye of apatient in applying a measured quantityof liquid to the eye; or a pouring cup from which a measured uanvtity of fluid trapped in the chamber o the stogiper may be Figure 7 is a sectional 1921. serial ne. mman.

y poured in laboratory work. everal embodiments of the invention are shown by way of illustrationin the accompanying drawing. In said` drawing- Figure 1 is a vertical axial section of a bottle having one form of measuring stopper applied thereto, the parts being in position to establish communication between the vbottle and the measuring chamber.

Figure 2. is a detail view of the stopper PAfrENroFr-'lcE-- shown in Figure 1,-withl the parts in position to shut olf communication between theV construction of passageway for the llow of liquid intothe. measuring chamber and the escape of airtherefrom.

Figure 5 is an inner end view' of the constructionshown in Figure 4.

Figure 6'is a sectional view showing a measuring stopper :combined with an eye cup and with a somewhat modified constructon; of passage closure; and

view of a stopper designed yfor measuring different quantities of liquid inthe measurmg chamber and dispensing the same by pouring, the form of passage closure correspondingto that shown in Figures 1, 2, and 3.

vReferring to Figures 1, 2, and 3, 1 re resents a Iliquid container, for instance, a t- .tle suitable to contain medicine v.and 2 repre- Stap` sents a measuring stopper therefor. per 2 is provided with a measuring chamber 31 having a removableclosure 4 and a filling stem 5`so that it is adapted to receive from the bottle 1 a measured quantity ofthe contents of the bottle.

IStern 5 is surrounded by a packing ory gasket 6 of cork or other suitable material, which fits tightly into" thel neck 7 of the bottle 1 in a manner to electually close the bottle against loss of its contents. This gasket constitutes avalve shell and is made' 'uli and another recess 11 that opens into communication with the air vent 9. Recesses 10 and 11 are so 'restricted in dimension in the direction of the circumference of the gasket 6 that rotation of the stopper relatively to the gasket and the bottle l will close the port I 8 and the vent 9 by bringing them opposite to solid portions of the gasket which receives the stem 5, as, for instance, when the stopper 2 is rotated tothe position shown in Figures 2 and 3. Ordinarily the gasket.

6, if made with properdimensions, will remain stationary in the .neck 7 y during rotation of the stopper 2 because of the greater area of contact between the outer circumferenceV of the gasket and the neck of the bottle than between ythe Ainner circumference of the gasket and the stem 5., However, frictional resistance to turning of the gasket `6 in the neck 7 may be increasedif desired through means of a rubber or other friction band'12, as shown in Figure 1. l

With a stopper constructed as shown in Figures 1, 2 and 3 and applied to a bottle .such as 1, the measuring chamber 3 will be promptly filled upon. inverting the bottle,

located in the .end of the stem 5 and communicate with the interior of the bottle through the bore 11, as show-n in said figures; or the vent may be given the lo' cation 9b and communicate with the same bore 10'L that leads to the port 8 as shown in Figure 7. l

Instead of having the wall of the measur-l ing chamber in the form of a mouth piece 2 as shown in Figures 1 and 4, it may be surmounted by an eye cup 2*, as shown in Figure 6; or it `may be in the form of a pouring cu 2", as shown in Figure 7; or a cup, regar less of its particular form, may be provided with' measuring graduations w, as shown in Figure 7. These will be of par ticula-r advantage, however, in a dispensin measure for laboratory work, as suggeste in Figure` 7.

I claim:

In a bottle stopper having 4a chamber for measuring la vportion of the contents of the bottle, and having a ported stem adapted by rotation in the bottle to bring the chamber into and out of communication with the bottle, a removable closure for the discharge end of the chamber, and a cup formed ,upon the Wall of the chamber andA projecting beyond said closure. l
